The specific features of diabetic microangiopathy include thickening of basement membrane with deposition of a transparent material.Diabetic retinopathy,neuropathy,cardiomyopathy,as well as diabetic foot are the main complications.It remains controversial whether intensive treatment may reduce the clinical renal end point events significantly,while evidence-based medicine confirmed that intensive treatment can reduce the trace and heavy proteinuria,neuropathy,and retinopathy.It will benefit the patients if comprehensive,and standard and,persistent treatments,are started as early as possible,and it consider the features of elderly patients.Managing Older People with Type 2 Diabetes Global Guidelines (IDF) and Chinese Elderly Diabetes Expert Consensus on Diagnosis and Treatment Measures point out that microvascular complications in elderly patients with diabetes closely related to the quality of life,to which we should pay great attention.Early prevention,early diagnosis,early treatment,reach the standard in early stage will be of important clinical significance for the prevention and treatment of senile diabetic microvascular lesion.

Glycosylated hemoglobin A1c(HbA1c)is the products of slow,continuous non-enzymatic saccharification reaction,which can reflect the average blood glucose of 2~3 months of the patients,and it is the most important index for long-term monitoring of glucose.There are so many methods for detecting HbA1c that America,Japan and Swede proposed their own standardized detection methods to reduce the difference laboratories.However,these methods were non-specific.A new method for was developed by International Federation of Clinical Chemistry and laboratory medicine (IFCC) in 2007,which was of high specificity,but which resulted in relatively low glycosylated hemoglobin.To avoid the confusion in reference value of glycosylated hemoglobin,average blood glucose was recommended by American Diabetes Association (ADA),European Association for the Study of Diabetes (EASD),and International Diabetes Federation (IDF).This paper review the origin of average blood glucose substituting HbA1c,relationship of HbA1c with average blood glucose,and the international multiple-center research of ADAG and its enlightenment,and we also discuss the relevant development in future.

Retinopathy of Prematurity is a retinal vascular proliferative disease.With the improvement of the medical care in China, retinopathy of prematurity (ROP) has become one of the main causes of child hood blindness in recent years.Several factors such as short gestational age, low birth weight and oxygen supplementation are the three major risk factors for the disease, however, the pathogenesis is still not clear.This review here aims to expand the etiology and pathogenesis of ROP and provide a theoretical basis for the prevention and control of the disease.

Purpose:To study the efficacy and toxicity of g emcitabine/cisplatin(GP) and gemcitabine/carboplatin(GC) in patients with advanc ed non-small-cell lung cancer(NSCLC). Methods:patients for GP: gemcitabine 1 000 mg/m 2,days 1 a nd 8 plus cisplatin 30 mg/m 2 days 1-3 or GC:gemcitabine 1 000 mg/m 2 , days 1 and 8 plus carboplatin AUC=5 day 1. Cycles were repeated every 3 weeks. Results:54 patients to GP and 52 to GC. The objective response rate(CR+PR)was 48.1% for GP and 44.2% for GC. No significant differences between arms were observed in response rate. No significant differences between arms we re observed in median time to progression(6.8 months GP, 6.2 months GC).GP arm h ad a remarkably higher incidence of grade nausea/vomiting Ⅲ-Ⅳ than GC arm(P

Objective To evaluate antitumor effect of adenovirus-mediated cytosine deaminase (CD) gene and 5-fluorocytosine (5-FC) on rectal cancer cells.MethodsCD gene was transinfected into HR-8348 rectal cacer cell lines with recombinant adenovirus mediation. The transinfection rate and expression of CD gene were detected. Plating efficiency and MTT method were used to examine inhibition of HR-8348 cell growth, and antitumor effect of CD/5-FC were evaluated on HR-8348 experimental tumor in nude mice.ResultsHigh transinfection effeciency and expression of CD gene were achieved in HR-8348 with adenovirus mediation. CD/5-FC system showed a remarkble effect of inhibition on plating efficiency and growth of the tumor cells transinfected with CD gene, but no act on tumor cells without CD gene transinfection. In a mixture of HR-8348 tumor cells with and without CD gene transinfection, CD/5-FC killed both types of tumor cells and revealed a powerful "by-stander effect". With nude mice experiment, 71.5% of inhibition of solid tumoral xenografts of HR-8348 cells was found.ConclutionCD/5-FC has significant antitumor effect on rectal cancer cells with adenovirus-mediated CD gene transinfection and has also "by-stander effect" on tumor cells.

Objective To study the expression of cathepsin B (CatB) and metallothionein (MT) in colorectal cancer tissue, and explore their association with lymphatic and hepatic metastasis. Methods Immunohistochemistry technique was used to assay the expression of CatB and MT in 82 cases of primary colorectal cancer, normal colon mucosa, and lymph node and hepatic metastasis. The relationship between the expressions of CatB and MT and the clinical stage or pathological grading of the colorectal cancer were analyzed. Results The rate of CatB expression in primary tumor, normal colon mucosa, and lymph node with metastasis and hepatic metastasis was 48.8%, 20.7%, 66.7%, and 59.1%, respectively, and that of MT expression was 53.7%, 26.8%, 71.4% and 72.7%, respectively. The rates of CatB and MT expression in primary tumor, and lymph node and hepatic metastasis were higher than that in normal mucosa tissue. The rate of coexpression of CatB and MT in lymph node and hepatic metastasis was higher than that in primary tumor and lymph node without metastasis. As regard to clinical stages, the positive rates of CatB and MT in Dukes C and D were higher than that in Dukes A and B (?2=11.024 4, 10.933 8, P
